Java is one of the most popular and widely used programming languages and platforms. It is an environmental platform that helps develop and execute programs written in any programming language.
Java is fast, reliable and secure. From desktop to web applications, scientific supercomputers to game consoles, cell phones to the Internet, Java is used in every corner.
About Java
-
Java is a simple language: Java is easy to learn and its grammatical structure is clear and concise. Java is C ++ based (so it is easier for developers familiar with C ++). Though Java has eliminated many confusing and underused features such as explicit pointers and operator overloading. Java also cares about memory management and provides you with an automated garbage collector. This collector automatically collects unused objects.
-
Java is a platform-independent language: applications written in Java, after compilation, into an intermediate language called bytecode (
Bytecode), part of the Java platform that is independent of the device on which the program is running. This makes portability very high for Java because its bytecodes can be run on any machine by a translator called the Java Virtual Machine (JVM), which allows Java to reuse the code.
-
Java is an object-oriented programming language: OOP or object-oriented programming simplifies a complete program by dividing it into a number of objects. Objects can be used as a bridge to stream data from one function to another. We can easily change data and functions according to program requirements.
-
Java is a trusted language: Java applications must be reliable because they are used in both consumer applications and critical mission applications, from Blu-ray players to navigation systems.
-
Java is a multi-threaded language: Java can perform many tasks simultaneously by defining multiple lines. For example, an application that manages a graphical user interface (GUI) while waiting for input from a list network connection uses another thread instead of the default GUI thread for both tasks. This helps maintain the GUI.
-
Java applications can create applets: Applets are applications that run in web browsers.
-
Java does not require any preprocessing: You do not need to import header files to create a Java application.
Therefore, Java is a very successful language and is becoming more and more popular.
Important points to get started
1. Understand the basics:
It is important to learn the basics of any programming language. This is the best way to start learning anything new. Do not be anxious, start learning language concepts. Get acquainted (gain, obtain) with present-day techniques that came from Acne.
2- Patience is a key principle:
Learning Java will be great because of the amount of language related content, but be patient, keep up the good pace, don’t rush. Mastering Java is a time-consuming process, and remember that even the best programmers start from scratch. So it’s not a big deal, just do as much as you can and keep going. Give yourself time, patience is the key to success.
3- Practice coding:
Once you are familiar with the basics, it is best to review your skills with regular practice. Real knowledge comes only when you apply what you have learned. As the saying goes, “Practice makes a man perfect.” So write more code than what you read. This will build your confidence. Remember that perfect exercise completes you.
4. Read about Java regularly:
Stay up-to-date on various topics in Java and try to learn more. This will help keep you interested in Java.
5- Group study
Group study is a better way to learn anything. This way you will learn new things about the topic because everyone comes up with their own ideas and you can discuss and solve your coding problems. Meet a typical group of people who want to learn Java.
Get help from a guide and read as many books about Java as possible. There are many good books on the market to help you learn Java.
Java startup
You can download Java. There are several versions of Java, choose a version compatible with your operating system and download.
After setting the Java environment correctly, run this simple program:
// A Java program to print GeeksforGeeks
public class GFG {
public static void main (String args [])
{
System.out.println (“GeeksforGeeks”);
}
}
Output:
GeeksforGeeks
If the programming environment is set up correctly and the code is written correctly, you should see this output on your console. This is your first Java application!
